b) Review of existing bicycle and pedestrian facilities and new facilities through the <br />TxState campus; and <br />c) Review of utility locations to determine potential conflicts and required adjustments. <br />1.2.2 Prepare preliminary layouts for three design options. <br />a) Option 1 will include maintaining existing right-of--way on LBJ from Sessom to <br />Holland and design a two or three-lane section based on available right-of--way. No <br />improvements or changes to Chestnut will be proposed and LBJ will remain two-way <br />traffic; <br />b) Option 2 will include construction of a three-lane section from Sessom to Holland <br />and acquire the necessary right-of--way to construct this section. No improvements or <br />changes to Chestnut will be proposed and LBJ will remain two-way traffic. <br />c) Option 3 will include conversion of LBJ and Chestnut to 1-way traffic. No right-of- <br />way will be acquired in this option. <br />1.2.3 Prepare one (1) typical section for LBJ and/or Chestnut for each option under 1.2.2. <br />1.2.4 Perform a drainage analysis that will include a drainage flood study prepared for the City <br />by Espey Engineers, and incorporate applicable elements into the design. <br />1.2.5 Perform geotechnical investigations to form the basis for construction and pavement <br />design recommendations, including waterline design, as well as locate topographic features that <br />may impact construction including: <br />a) Perform a visual condition survey of Chestnut Street. The Engineer will survey the <br />1,400 linear feet of pavement of Chestnut Street in order to identify the distress <br />mechanisms and extent of distress. In addition, the Engineer will visually inspect the <br />roadway to identify distress types including cracking (fatigue, longitudinal, and <br />transverse), block cracking, bleeding, and raveling; <br />b) LBJ Drive: Drill and sample 8 borings to a depth of 10 feet. <br />c) Two retaining walls: Drill and sample 4 borings to a depth of 25 ft each. <br />d) Chestnut Street: Drill and sample 4 pavement borings to a depth of 5 ft each. <br />e) Perform a laboratory investigation to Consist o£ <br />i) moisture contents; <br />ii) Atterberg limit determination; <br />iii) gradation analyses; <br />iv) unconfined compression tests; <br />v) corrosion potential; <br />f) Prepare an engineering report to include: <br />i) plan of borings and logs of borings; <br />ii) results of laboratory testing; <br />iii) flexible pavement thickness design for LBJ Drive using TxDOT procedures; <br />iv) geotechnical parameters for retaining walls including allowable bearing pressures, <br />4 <br />
